ILLUMINATOR INVENTOR Q/Llfuy ATTORNEY provide a device which Patented June 15 1926 UNITED STATES OSCARA. HUG, or BROOKLYN, New YORK.

ILLUMINATOBI.

Application filed September 9, 1925. Serial no. 55,222.

The main object of this invention is to may be mounted upfinger, or any other on a pen, pencil, or a the purpose of 1lluconvenient support for minating a small area such as anewspaper] or a writing pad in the dark.

'Another object is to provide an illumin-' ating device having means thereon whereby it can be quickly attached to the finger or a fountain pen or a similar article.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing. 1 r

Referring briefly to thedrawing, Figure 1 is a perspective View, showing theilluminator mounted upon a fountain pen which is being gripped in the hand in writing position.

Figure 2 is a top plan view of the illumlnator.

Figure 3 is a longitudinal sectional elevational view of the illuminator.

Figure 4; is an enlarged sectional elevational View of the rear end of the apparatus.

Referring in detail to the drawing, the numeral 10 indicates the barrel of a fountain pen. The device is adapted to be mounted to the upper end of the fountain pen barrel. trated herein is adapted to be used in various manners and is not wholly restricted for use with a fountain pen. The device essentially consists of an arcuately curved plate 11 which extends vertically and has projecting horizontally therefrom a tubular member 12 rectangular in cross section in which a pair of conductor bars 13 and 1a are secured. These conductor bars extend from one end of the tubular member 12 and are separated from each other by an insulator strip 15. The conductor bar it lies below the conductor bar 13 and has at its outer extremity a hollow sleeve 16in which threads are formed which are adapted to be engaged by a socket 17 of a filament lamp 18. Upon the outside of the sleeve 16, a restricted or mouth end 19 of a parabolic reflector 20 is mounted. The conductor bar 13 extends from the end of the tubular member 12, which extending end is flexible and is adapted to normally and yieldably enter into contact with one of the terminals of the socket 17 The tubular member 13 and the curved plate 11 is formed of some insulating material such as rubber or paper so that one The illuminating device illus-- conductor bar is entirely insulated from the insulating member. A coil spring 21 has its length curved circularly and its ends are connected to the curved plate 11 forming a yieldable member, which normally constricts itself about the object which is passed thru the area 22 bounded bythe .spring.

From the inner ends of the conductor bars 13 and 1 and enclosed within the tubular member 12, a pair of terminals 23 and 24 are provided. These terminals are identical in construction and are provided with openings 25 into which thelead wiresof an energizing circuit are inserted. The terminals are hollow and at their upper ends are provided with threads which are engaged by plugs 2t, the plugs being adapted to retain a hemispherical ball plunger 27 and a spring 28 in place in the terminal. The lower ends of the terminals 23 and 24 below the open ings 25 are sealed and provide a terminal upon which thehemi-spherical plungers 27 are adapted to seat when no lead wires are inserted thru the openings 25. i

A pair of lead wires are connected to these terminals '23 and 24: and course from the wrist .of a person as a single conducting cable '29. This cable leads to a plug 30 which is connected to a source of energy such as a cell 31. The cell is :mounted in 'a gifrdle' 32, which latter is secured to a wrist strap 33.

The device is used in the following main ner, when reading or when writing, which latter use is illustrated in Figure 1. The cell 31 is strapped to the wrist of the hand and the illuminating unit, consisting of the parts illustrated in Figures 2 and 3, is

mounted upon the upper end of a fountain I pen 10 by slipping the coil spring ring 21 around the barrel of the fountain pen. The curved plate 11 rests upon the periphery of the barrel and serves to press the entire projecting structure of the illuminator consisting of the parts 12, 13, 1e, and 15, and the reflector unit 20, together with the filament lamp 18, from falling. When the ends of the lead wires in the cable 29 are inserted into the openings 25 of the terminals 23 and 24, the helm-spherical plungers 27 are lifted and yieldably remain in contact with these wires thru the tension of the springs 28. In this manner, the lead wires are retained in electrical contact with the terminals 23 and 2e and may be readily released by simply pulling the same out of the openings. The circuit passes from the cell 31 thru the lead wires in the cable 29, thence thru the conductor bars 13 and 14-, finally passing thru the filament lamp 18, illuminating the same. The reflector 20 depends downwardly and concentrates the beam of light directly in front of the thumb 34 and forefinger 35 of the hand, which illuminated area the pen finds itself in when writing. 7

Various other uses may be found for the illuminating device. When reading, the coil spring ring 21 may be strapped upon any one of the fingers or upon a pencil in the vest pocket. When using the device as an accessory in producing repairs on articles in darkness, the device may also bestrapped to one of the fingers, thus permitting the user to use both hands on repairing an article instead of using one hand for repair of the article and the other for operating the flashlight.

I claim H 1. An illuminator comprising a cell strapped to the wrist, an illuminating unit used in combination with a fountain pen comprising a vhollow member having a curved plate extending at right angles from one end, said curved plate being adapted to seatupon the barrel of the fountain pen or the like, a pair of conductor bars extending lengthwise in the hollow member and being mutually insulated, said conductor bars eX- tending from one end of the hollow member, one above the other, a sleeve in the lower conductor bar, a filament lamp adapted to be mounted in said sleeve, a reflector mounted 011 said sleeve around said filament lamp, the conductor bar beingflexible and forming the opposite terminal for contacting with one of the terminals of the filament lamp, a lead wire extending from the cell to the hollow member, means for attaching said illuminator unit to a fountain pen, and means for securing the lead wires to the conductor bars.

2. An illuminator comprising a cell strapped to the wrist, an illuminating unit used in combination with a fountain pen comprising a hollow member having a curved plate extending at right angles from one end, said curved plate being adapted to seat upon the barrel of the fountain pen, a pair of conductor bars extending lengthwise in the hollow member and being mutually insulated, said conductor bars extending from one end of the-hollow member, one above the other, a sleeve in the lower conductor bar, a filament lamp adapted to be mounted in said sleeve, a reflector mounted on said sleeve around said filament lamp, the conductor bar having the sleeve forming one terminal, the opposite conductor bar be.- ing flexible and forming the opposite terminal for contacting with one of the terminals of the filament lamp, a lead wire extending from the cell to the hollow member,

means for attaching said illuminator unit,

to a fountain pen, terminals projecting thru the hollow member and integral with the conductor bars, said terminals comprising hollow elements, hemi spherical plungers in said terminals, threaded plugs closing the upper ends of said terminals, and springs in said terminal between the plugs and the hemi-spherical plungers for lowering the latter, said terminals having openings for insertion of the lead Wires therein.

In testimony whereof I afiix my signature.
